Percutaneous, Antegrade Access of the Superficial Femoral Artery can be Safely Used in Procedures for the Treatment of Lower Extremity Limb Ischemia

Recent studies have shown that antegrade access for treatment of infrainguinal peripheral vascular disease is associated with decreased radiation exposure and contrast use without a significant increase in access complication, although data are limited on antegrade superficial femoral artery (SFA) access for larger sheath sizes. We aim to describe a single institution's contemporary experience with percutaneous antegrade SFA access.A retrospective review of percutaneous, infrainguinal endovascular interventions for arterial occlusive disease at a major academic institution was conducted between 2018 and 2020. Antegrade, percutaneous, SFA access cases were included. Information on demographics, indication, sheath size, arteries treated, type of intervention, concurrent pedal access, closure devices, and complications was collected and analyzed.A total of 45 patients with an average body mass index of 25.25 were identified. Indications for intervention included tissue loss (64.4%), rest pain (6.7%), claudication (13.3%), and acute limb ischemia (11.1%). Of which, 80.0% of patients had multilevel interventions. Angioplasty was performed in 68.8% of patients, stenting in 8.3%, atherectomy in 15.6%, and thrombectomy in 7.3%. Nearly a quarter of cases involved concurrent pedal access. Maximum sheath size was 4F for 4.4% of patients, 5F for 28.9%, 6F for 46.7%, 7F for 11.1%, and 8F for 8.9%. The closure device was utilized in 75.6% of cases, with no closure device failures. In the entire cohort, there were no demonstrated access site complications.This study demonstrates percutaneous, antegrade SFA access for complex endovascular interventions for infrainguinal occlusive disease can be effectively utilized, even with larger sheath size. Moreover, routine use of closure devices is safe, improving patient comfort and expediting time to ambulation.
